hi I have a 2001 sportsman 500 HO. I replaced pulser coil after recoil self destructed and acts like the symptoms of the DREADED bad exhaust cam. Cam is fine and ran great before it happened. I have been through every thing i can think of (carb x 2, throttle cable adjustment throttle actuator, spark plug, different flywheel, boot for carb to engine) starts and idles fine, just bump the throttle slightly,or try to feather it, it misses and backfires then dies. Trying to avoid taking it to the stealer. prices are way out of line, bad attitudes, and 4 to 5 weeks behind. I,m boarder-line for using drugs and or C-4 Help!? John K
